I bought this super inexpensive frame for my first home made build, only to realize I didn't do enough research. 

The 1103's I bought didn't fit the mounting holes, so I created some simple adapters to make them fit the 3-hole pattern. They also conveniently added enough length to make it a true 2"

I also designed a swappable battery mount so I could double up the varous 1s batteries I already had to run it at 2s. I also made an adapter for a li-ion 2s, but it flew a bit sluggish. 

Print the main parts in PLA plus or other durable material (abs/nylon, etc.)

Battery slings should be printed in TPU for a little flexibility. They fit nice and snugly in the mount and around the designated battery sizes.
